Actually I do have a question - how safe is this for eyes (human or animal?) and what changes are needed to make it safer?
How about measuring through translucent or transparent surfaces? Should work as is if there is no reflection (e.g. measurement at Brewster’s angle for this wavelength) but is it possible to TOF multiple reflections from? Or multiple depth slices (e.g. by gating TOF to specific depth ranges? 1ns=~1ft=~30cm

- iliasam 7y agoAs it was answered, you could read about safety here: https://github.com/iliasam/OpenTOFLidar/wiki/Laser-Safety https://github.com/iliasam/OpenTOFLidar/wiki/Laser-Safety Measuring through translucent or transparent surfaces is theoretically possible (TDC is supporting multiple measurements), but received pulse width is too high now - it could be > 30ns after amplifier.
